I bought a Hsu VTF-2 recently, and though it's more than I *need* it's a a great boon to my system, music or movies.
SVS has comparable subs (though you can't vary the sealed/ported configuration like a Hsu VTF sub), and offers free shipping to you, and return if you dislike them.
Both Hsu and SVS have speaker packages, I've read some glowing reviews of the SVS combo sets. If I was shopping for a speaker set, I'd be inclined to try SVS first.
